Does anyone know how to get rid of the automatic HDR on Blender 2.8
You can get rid of the hdri by using the rendered viewport mode or switching it with a different hdri in the user preferences.

In order to make glass transparent and refractive in eevee you have to enable screen space reflection and check the refraction option.



Then you have to go to the material settings and enable SSR there as well. I found that the alpha hashed blendmode works best.
